what can you do in las vegas in 3 days?

go clubbing

I think three to four days in Vegas is plenty of time. You should see the fountains, a show or two, eat good food and walk the strip to see of the hotels.

You can't club all day... I just got back and during the days I went hiking and at night I hit The Strip.

I highly recommend seeing "Valley of Fire" and "Red Rock Canyon". You should definitely check them out! Not to mention, The Hoover Dam and Lake Mead!

You can do a lot. If you are planning to gamble a lot I would suggest joining one of the players clubs. http://www.allvegasdeals.com/category/players-club...

There are a lot of show options you can check out as well as a variety of top restaurants. I would suggest hitting up a pool like the Wet Republic if you plan on being there in the summer.

Alot you should eat at Nove Italiano one of the best Italian restaurants in the world. It is in the Palms you will have a blast in 3 days.

Not as much as there is to enjoy. See a cirque show, enjoy a buffet, visit a club, gamble, watch the eye candy at the pool, and rest

Gamble. Visit the Stratosphere. Get drunk. Go see the Bellagio fountain. Go ride the New York New York ride. Get drunk. Lose money. Get drunk. Sleep. Swim. Die of dehydration. Eat. Get drunk. Have sex. Get drunk. Regret.
